LUBRIGATING DEVICE FOR INTERNAL-COMBUSTION ENGINES'.

Specification of Letters Patent. Patented )May 20, 1919,

Original application led September 15, 1916, Serial No. 120,216. Divided and this application led October 23, 1917. Serial No. 198,006.

To all 'whom t may concern.' n

Be it known that we, CHARLES JULES MGEVET, manufacturer, and LUcrEN PICKER, engineer, both citizens of Switzerland, residing at Geneva, Rue Confederation of Switzerland, have invented certain new and useful Improvements in Lubricating yDevices for Internal-Combustion Engines, of which the following is a specification.

The invention relates to a lubricating device for internal combustion engines andis a division of our co-pendin application Serial No. 120216 filed Septemoer 15, 1916. In this lubricatino' device the casing of the engine is adapted to contain an oil bath maintained at a constant level by a feeding tank, which is tightly closed, is at a higher level than the oil bath and is in communication with the latter through a pipe, the lower end of which is at the level of the free surface of said bath, said level being capable of being regulated at will while the engine is running by raising and lowering the whole tank and pipe.

The cover of the tank may be provided with a member which, when the cover is screwed home, opens the passage for the oil fromrthe tank into the pipe, and which further permits of said passage being closed before opening said cover, for the purpose of avoiding the emptying of the tank when the cover is removed.

Oil taken from the engine casingmay circulate in a cup into which the connecting rod of the piston dips at each stroke and in which the oil level is regulated by means of a sluice, the level of the oil being variable at will while the engine is running.

The annexed drawings show by way of example an internal combustion engine pro vided with an oiling apparatus in accordance with the invention.

Figure 1 is a vertical cross section of the engine.

Figs. 2 and 3 are detail views of the appara-tus.

Referring to the drawings, the rod or rods c connecting the piston or pistons bto the crank shaft d ofthe engine is or are provided with a conduit F for the lubricating oil; for this oil a pump H is provided which, when the engine is running, is operated by an eccentric disk I on a cam shaft g driven by gearing from cam shaft cl and Malatrex 7 & 9, in the4 by a counter actingspring J. The pump communicates by the horizontal pipe K, seen from one end in Fig. 1 with the cups G, only one being seen in the drawing. These cups are each provided with a sluice or weir L adapted to close more or less an opening L (Fig. 3) in the side of the cup.

Eachsluice or weir is at the end of a lever secured to a rod operated exteriorly of the casing by a handle M. A hermetically closed tank N fitted with aV screwed rod O for adjusting it at different levels supplies the oil for feeding the casing through a pipe P. The cover N of the tank carries the rod Q, a valve R and a counter acting spring R.

The operation of this form of the oiling apparatus is as follows:

The piston pump H draws up the oil through an interposed filter, not shown in the drawings, from the oil collected in the hollow base or casing of the motor and forces it into the horizontal pipe K and from there into the Cups Gr. The conduits F provided at the lower end of the connecting rods c will at each stroke catch a drop of oil by skimming the surface of the oil containedin the cups Gr. If the sluices entirely shut the openings L the oil level in the cups Gr will` be as high as possible and the lubrication Y will be more abundant, because the connecting rods enter more deeply into the oil. In order to lessen the lubrication it is only necessary to lower more or less the sluices H by means of handle M, as the oil level in said cups Gr becomes deeper.

The pipe P extends downward to the surface of the oil bath for the following reason: As the tank is tightly closed at its upper end the oil therein remains in equilibrium but, if the level of the oil bath -is lowered,

an air bubble enters through the pipe P into 'the tank and allows in place thereof a cor'- responding quantity of oil to descend in order to reestablish the former level of the oil bath. Now the tank is located at a higher level which can be easily altered by adjusting the supporting screw O in which case the whole tank N with pipe P is raised or lowered; it follows that the oil level in they base becomes higher or deeper.

The tank N is always kept tightly shut by a cover N but even when opening this cover the oil cannot escape. To efl'ectthis the plug is fitted with the rod Q which while the cover is screwed home Lmaintains the valve R in the open position. But when the cover is removed the valve R in the bottom of the tank is closed by the action of the spring R and thereby prevents the emptying of the tank when opened for refilling. f

Claims:

1. In a lubricating apparatus for internal y combustion engines and the like, the combination with a casing havingan oil chamber therein, and a device for automatically feeding oil thereto to maintain a predetermined quantity of oil therein, of a plurality of receptacles into each of Which a connecting rod dips in the operation of the engine, and in the side of each receptacle there is an overflow opening, a Weir for each receptacle, and means on which all the said Weirs are mounted and are separately secured and by which all the said Weirs are simultaneously adjustable to position in relation to the overflow openings in the said receptacles.

2. In a lubricating apparatus for internal Copies of this patent may be obtained for ve cents each, by addressing the Commissioner combustion engines and the like, the combination with a casing having an oil chamber therein, and a device for automatically feeding oil thereto to maintain a predetermined quantity of oil therein, of a plurality of receptacles into each of which a connecting rod dips in the operation of the engine, and in the side of each receptacle there is an overflow opening, a rod, a. plurality oi levers connected at corresponding ends to said rod, a Weir at the opposite end of each lever adapted t control the overflow opening in one of the said receptacles, and means for rocking said rod so as to simultaneously adjust the positions of the said levers and Weirs connected thereto.

In testimony whereof We haveailixed our signatures in presence of two Witnesses.
